The pulp and paper industry continues to grow and produces large amounts of fly ash waste from the biomass combustion process. Alternative waste management besides landfills needs to be developed so that the use of fly ash can be ecologically and economically acceptable, such as for land applications in industrial plantations, especially on peat soils. This paper presents the results of the analysis of micro nutrients from fly ash from pulp and paper mill waste that can be used for agriculture and forestry. The elemental content of boron (B) and zinc (Zn) can be detected in fly ash samples both by lauryl amine extraction and stearyl amine extraction, where the optimum amount is obtained using 15 gram of fatty amine and n-hexane solvent with a processing time of 4 hours. Stearyl amine gives a higher yield than lauryl amine because it has a longer saturated carbon chain.

One of the latest innovations in textile waste treatment is advanced oxidation processes (AOPs) methods using an oxidizing agent capable of producing sulfate radicals (SO4â€¢). This study aims to determine the activity of the Mn/Carbon sphere catalyst in the oxidation process, reduce the dye content by using a combination of peroxymonosulfate (PMS) and Mn/Carbon sphere catalyst as an oxidizing agent, and determine the optimum conditions in the process of reducing dye levels in the water. A hydrothermal process carried out the catalyst synthesis process to produce black carbon from D-glucose solution, then impregnated with variations of 3% and 5% of Mn metal. The degradation of methylene blue (artificial waste) of 25mg/L (1:10 dilution) was carried out for 120 minutes with variations in the catalyst mass of 0.001, 0.002, 0.003, and 0.004g and the mass of PMS 0.01, 0.02, 0.03, and 0, 04g in 100ml sample. Mn/Carbon sphere catalyst was able to activate PMS and was able to degrade methylene blue by 88.16%. The optimum condition for reducing the methylene blue levels in the water is at a concentration of 1g/L PMS and a Mn/Carbon sphere catalyst (5% Mn metal) 0.5g/L with an efficiency of 88.16%.

Potensi Pengembangan program pemberdayaan masyarakat harus berorientasi meningkatkan kesejahteraan masyarakat dengan menggunakan sumber daya yang ada. Program harus mempertimbangkan keunggulan yang dimiliki oleh suatu daerah. Oleh karena itu penting untuk melakukan analisis potensi desa sebelum mengambangkan sebuah program pengabdian kepada masyarakat. Kuliah Kerja Nyata (Kukerta) merupakan salah satu bentuk program pengabdian masyaraat yang dimotori oleh mahasiswa dan dibimbing langsung oleh Dosen Pembimbing Lapangan. Dari tahun ke tahun program Kukerta terus berkembang menyesuaikan kondisi yang ada. Dalam rangka untuk memasimalkan rancangan program yang dilaksanakan, perlu dilakukan analisis potensi desa terlebih dahulu. Dalam melaksanakan analisis potensi desa, focus pemetaan akan dilaksanakan pada sector (a) perkebunan dan pangan, (b) pariwisata, (c) tambang dan energi, (d) industry, serta (e) kesehatan. Lima indicator tersebut dijadikan sebagai acuan untuk penyusunan program. Data diperoleh melalui survey oleh mahasiswa Kukerta pada tahun 2022. Setelah itu data akan ditabulasi dan dipetakan untuk kemudian dijadikan bahan penyusunan model yang baru.

Lack of education in waste management has led to a large amount of waste being dumped in landfills. Organic waste is the largest type of waste disposed of in landfills. If organic waste is not managed properly, it can cause unpleasant odors in the environment and become a risk factor for global warming and explosions in landfills. Until now, waste management, both organic and inorganic waste, is still a challenge. This is also the case in RW 02 Kelurahan Air Putih. The community directly disposes of household waste without sorting the waste by type. In addition, the community also does not know how to process organic waste into useful items such as eco-enzyme and eco-enzyme processed products, namely cleaning fluids. This community service activity aims to increase community knowledge and skills on how to process household organic waste into eco-enzyme and liquid soap made from eco-enzyme. The targets in this activity are housewives in RT 06, RT 07, and RT 08, RW 02 Air Putih Village. The method used in this community service activity is socialization and training on how to make eco-enzyme and multipurpose liquid soap. The results obtained from this activity are the increased knowledge and skills of the community in processing organic waste into eco-enzyme and multipurpose liquid soap. The community is also enthusiastic and interested in making these products again in their homes.
